Ukiah's Safeway store was evacuated Sunday night after a pile of cardboard boxes caught fire and filled the building with smoke, the combined Ukiah Valley Fire District and Ukiah Fire Department reported.

The fire was reported around 7:50 p.m. Dec. 29 at 653 South State Street, and Chief John Bartlett said a pile of flattened and bound cardboard boxes had caught fire for what is still an undetermined reason.

The fire then spread to a pile of pallets and filled the store with smoke. Bartlett said the store was evacuated and no injuries were reported.

There was only minor damage to the building, and firefighters helped clear out the building using "smoke ejectors," which he described as akin to large fans.

The Hopland Fire Department and the Redwood Valley-Calpella Fire Department also responded.
